Hey, does anyone think that it's possible to only get a data plan, and then use Google Voice for calls and texts? I thought that might be possible..but then I figured there might be some issues. 1. I've read somewhere that Google Voice's app only refreshes it's texting inbox every 5 minutes. That sucks. 2. When calling someone on Google Voice, doesn't it first call your number then call the person you are trying to reach? That would mean I have to buy minutes. Are there any other problems with using Google Voice + Data Only Plans? Then I'd only have to buy the Nexus One Unlocked and put in my AT&T SIM card, right?
